This market will resolve according to the candidate who wins the nomination for the Democratic Party to contest the NH-01 congressional district seat in the U.S. House of Representatives in the 2026 midterm elections. The Democratic primary will take place on September 8, 2026. If no nominee is announced by November 3, 2026, 11:59PM ET, this market will resolve to "Other". The resolution source for this market will be a consensus of official Democrat sources, including https://democrats.org/. Any replacement of the nominee before election day will not change the resolution of the market.

Trader consensus on Polymarket heavily favors Stefany Shaheen as the NH-01 Democratic primary winner, with 62% implied probability, driven by her strong fundraising—over $1 million raised—and high name recognition as daughter of U.S. Sen. Jeanne Shaheen. Recent polls, including an August American Research Group survey, show her leading incumbent Chris Pappas 42%-28%, boosting her edge amid undecided voters. Maura Sullivan holds 25% on veteran status and 2018 campaign experience, while Carleigh Beriont's 11% reflects progressive grassroots momentum; Heath Howard trails at 4.3%. The September 10 primary looms as the key catalyst, with debates potentially shifting odds further.
